Abstract
A quick release fitting for securing equipment, such as seating, to floor or ceiling tracks of T-shaped internal channel section comprises a first member securable to the seating and a second member rotatable through a quarter turn in the first member, the second member including a T-shaped end complementary in shape with the channel and engageable therein by insertion in the channel with the cross-member of the "T" extending along the channel and subsequently turning the second member through a quarter turn. An alternative, retractable fitting comprises a body portion adapted to be fitted in a floor structure and a captive insert member held captive in a bore in the body portion and movable between a retracted position flush with the upper surface of the floor structure and an upper, projected, position for engagement with a seat mounting for example, the insert member being spring biased towards its projected position and being retainable in its retracted position by cooperating bayonet formations on the body portion and insert member.
